What do antiproliferative agents do?

Antiproliferative agents, also known as antimetabolites, inhibit cell-cycle pathways to limit T- and B-cell proliferation and thereby reducing the cytotoxic response directed toward the cardiac allograft.

Why is therapeutic drug monitoring important for immunosuppressants?

Immunosuppressants require therapeutic drug monitoring because of their narrow therapeutic index and significant variability in blood concentrations between individuals. The variability in blood concentrations can be because of factors like drug-nutrient interactions, gender influence and polymorphism.

Which laboratory test should be monitored to assess for complications of immunosuppressive therapy?

Therapeutic drug monitoring (TDM) plays a pivotal role in the management of immunosuppressive therapy, ensuring that the right drug concentrations are achieved and maintained for each individual patient.

What are Antirejection agents?

Immunosuppressants are drugs or medicines that lower the body’s ability to reject a transplanted organ. Another term for these drugs is anti-rejection drugs. There are 2 types of immunosuppressants: Induction drugs: Powerful antirejection medicine used at the time of transplant.

How do antiproliferative drugs work?

Drug-eluting stents elute antiproliferative drugs inhibiting vascular smooth muscle cell proliferation, which occurs in response to injury and thus prevents restenosis.

What is antiproliferative effect?

Medical Definition of antiproliferative : used or tending to inhibit cell growth antiproliferative effects on tumor cells.

What do you monitor for immunosuppressants?

Which immunosuppressant medication does not require therapeutic drug monitoring?

Azathioprine, steroids, anti-lymphocyte globulin, and OKT3 Monitoring the blood or plasma concentration of these drugs is not considered worthwhile as they all have relatively wide therapeutic indices. The three agents are generally given in fixed doses and are not subjected to therapeutic drug monitoring.

Why is therapeutic drug monitoring needed?

These tests are used to monitor blood levels of drugs that have a narrow range in which the drug is effective but not toxic. In addition, some drugs require monitoring because the amount of drug given does not correlate well with the amount of drug that may reach the blood.

What is the best specimen for drug monitoring serum or urine?

Serum is the preferred specimen for therapeutic drug monitoring, because drug concentrations in the specimen reflect the drug’s disposition at collection time. When the time and amount of the previous dose are known, the measurement can be compared with a predicted blood concentration of the drug.

What are the pros and cons of xenotransplantation?

There are pros and cons to Xenotransplantation. Xenoplantation aims to increase organ availability, it has the potential to open up new areas of research, and could end transplant list. The cons include high rejection rate, moral/ethical issues, and transfer of diseases from animals to humans.

Is diltiazem an immunosuppressant?

Although direct immunosuppressive properties of diltiazem are unlikely, diltiazem could support immunosuppression by altering CsA metabolism, and promoting accumulation of certain metabolites.

How are anti proliferative drugs used in medicine?

Sustained release of the drug coated onto drug-eluting stents is essential for the maintenance of the long-term patency of intravascular stents. Currently, anti-proliferative drugs with programmed pharmacokinetics are widely used in clinical practice.

How is MMF used as an antiproliferative drug?

Antiproliferative Drugs. MMF and azathioprine, both antiproliferative drugs, are used as part of immunosuppressive regimens in combination with calcineurin inhibitors and corticosteroids but MMF is most commonly used.299 Both inhibit inosine monophosphate dehydrogenase and share some antiviral actions with ribavirin,

Which is the best anti proliferative drug for RA?

Many AID, including severe cases of RA, SD, MG, PM, PS, SS, GS, and PG, are treated with anti-proliferative drugs such as methotrexate, azathioprine, or cyclophosphamide (refer to Chs.
